A Ferris wheel is moving at an initial angular velocity of 1.0 rev/59 s. If the operator then brings it to a stop in 3.1 min, what is the angular acceleration of the Ferris wheel

Explanation:

Given

initial angular velocity

-- Initial time

--- final angular velocity (when the wheel stops)

Required:

Determine the angular acceleration ()

The angular is calculated using the following formula

Convert time to seconds:

Convert angular velocity to rad/s

Substitute in the required values, the expression becomes:

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
